  ### New features

  #### Limit notifications

  Atoti Limits now supports sending notifications to the UI based on server events. See [Sending Custom Notifications](../../../dev/dev-extensions/custom-limits-notifications) for more information.

  #### Audit service

  The audit service has been added to Limits, including new dedicated screens to display audit. For more information, see [Audit History screen](../../../user-ref/audit-screen).

  #### Notification service

  The notification service has been added to Limits, including a new notification centre in the UI to manage your notifications. For more information, see [Notifications in the UI](../../../user-ref/ui-notifications).

  #### Workflow file attachments

  You can now save files as attachments at each step of the default workflows.
  This way you can upload files such as emails, screenshots, or other relevant documents directly to the workflow as evidence.

  For details on adding this to your workflow see `Defining Task Spring Beans`.

  #### Expired limits

  Expired limits are now visible in the limits viewer. For more information, see [View, edit, copy and delete limits](../../../user-ref/using-limits/view-edit-limit).

  #### Historical difference in audit

  The audit log for each incident now includes a record of historical differences, letting you easily track what has changed between the current and previous evaluations and understand the impact on the incident.

  #### Streamlined breach review

  You can now review limit incidents from an incident’s linked dashboard. For more information, see [Review incidents](../../../user-ref/manage-incidents/review-incidents).

  ### Improvements

  #### Nested temporary limits

  Temporary limits are now displayed as sub-rows of their source limits in the Limits Viewer screen.

  #### Atoti Server upgrade

  Atoti Limits has been upgraded to Atoti Server 6.1.3.

  #### Project Customizations

  We have added a new [Customizing the Starter](../../../dev/getting-started#customizing-the-starter)
  section to the documentation. This section provides instructions on how we recommend configuring
  and customizing the starter project to suit your needs.

  #### Error handling

  The APIs for validation errors and error handlers have been updated to improve error handling in the UI.
  See the [4.1 migration notes](./migrate-4.1#validation-error-changes) for the list of changes to migrate your custom errors and/or error handlers.

  #### Performance

  Additional enhancements have been made to improve the performance of limit evaluation and creation.
